dude do not just do straight pipe...its gonna sound like s***.
what you need to do is just go to tractor supply or summit and order two 2.5 inch resonators....($20 bucks each)
then just get the rest of the piping done and have one in the middle and one toward the end and it will sound awesome and be cheap!
Borla is an excellent brand. But I'm sure the price matches the product.
Any suggestions? I hear flowmaster is out of the question as far as being able to "flow"?
